Method and device for determining flight path in high precision based on polynomial fitting, and electronic equipment

Abstract

The invention discloses a method and device for determining a flight path in high precision based on polynomial fitting, and an electronic device. The method comprises the steps that N frames of videoimages shot by a flight device in the flight process are acquired, and each frame of video image corresponds to a time point; shooting center space position information corresponding to each frame ofvideo image in the N frames of video images is determined; according to the time points corresponding to the N frames of video images and the spatial position information of the photographing centercorresponding to the N frames of video images, a polynomial fitting function is used for conducting curve fitting, a flight path curve of the flight device is determined, wherein the polynomial fitting function comprises three polynomials, and each polynomial takes a flight time parameter of the flight device as an independent variable; and a coordinate value corresponding to one direction corresponding to the space rectangular coordinate system of the flight device is used as a dependent variable. High-precision determination of the flight path of the flight device is achieved, and the cost required for determining the flight path of the flight device and the increase of the additional weight of the flight device are reduced.

Description

technical field [0001] The invention relates to the technical field of navigation and positioning, in particular to a method, device and electronic equipment for determining a flight trajectory with high precision based on polynomial fitting. Background technique [0002] At present, flying devices such as unmanned aerial vehicles play a very important role in many fields, and how to accurately obtain the flight trajectory of the flying device is very important for better application of the flying device. [0003] In related technologies, an inertial navigation device or a satellite positioning system is usually installed on the flying device to record the location information of the flying device in real time, so as to obtain the flight track of the flying device. But, because the weight of inertial navigation device or satellite positioning system is bigger, can increase the weight of flying device, so this mode of installing inertial navigation device or satellite positio...
